Notice that there's no yellow? I'd replace the yellow drum. It's shorting out the HVT. =^..^=

Hello,

- all 4 new drums
- genuine toners all time of usage

, but not good printing.

What is your opinion?
- Transfer belt? I do not have another one, to change it :-(
- Voltage problems?
- Lasers problems?

Is that elliptic thingy supposed to appear on the first page?

Wow that page hurts my head. Did B.C's advise to change yellow work if you can still remember?

Those are the worst sample pages to print to try and get an idea there.
Then save the snapshot of it as a PDF so we can see the thing.
Download and print a color test chart.

Will have a good look at the transfer roller in the path and the belt. Take those out and take a pic of both the roller and the transfer belt. Its not the laser. You can see the void valleys from the texture of the paper were the transfer is to weak to make the toner jump another 10 microns more. Remeber something about transfer pressure timing?

I gave out int. transfer belt and make photo, and make photo of transfer roller, but now I remember, I changed this spring: A6DR702701 in coveyance section: it could be the possibility of poor printing quality?
After the side cover is closed, the conveyance mechanism put the transfer roller down. Which is the right position of transfer roller after closing side cover? Up or down?
I make paper jam (open the side cover, when it printing) and the transfer roller was up.
I make paper jam and put out itb. transfer belt and the picture at the ITB before reaching transfer roller was at poor quality. What do you think? The customer did not changed the drums (and he lie to me?)

Except for the ding in the belt, both roller and belt looks ok. The picture with the image on the belt shows that the transfer is bad. Looking at that most of the image stays on the belt and does not get transferred.

Make sure the HV makes proper contact. Also make sure the roller is pressing against the belt. The gears to lift the roller could be installed out of position.

Sure those ellipses on the sample print should be there?

Yes elipses are in the picture printed from computer.

I wrote: The picture at the transfer belt is BEFORE it reaches transfer roller! It is transfered right from drums!

Will have to disagree with you on that statement. It can't develop an entire image on the belt before transfer.
The image you got there was on the top of the belt. The transfer belt cleaning blade will be next in line.

Right from drums wrong from belt to paper.

Ok wow reconsidering this. The image is on the bottom of the belt ain't it.
Did not think you can stop a machine at the point. Well my bad again...

Call me Mr Assumption...

If it looks like the belt and it smells like the belt please change the belt.
You did change all the drums. And you did clean the laser glass.

If that is primary transfer then the transfer quality is bad.

Guess i will take a break from posting stuff. Getting hammered.
